MATERIALS AND METHODS:
A literature search was performed in the PUBMED database with the terms MESH (”Hemangioma”[Mesh]) AND (Persistent Left Superior Vena Cava[Mesh]), without finding any results available. A new search was then performed with the terms ”Persistent Left Superior Vena Cava” AND ”hemangioma” finding 6 articles, of which only 1 described a similar pathology, but in an adult patient. To develop the literature report, a new search was performed with the terms (”Hemangioma”[Mesh]) AND (”Neck”[Mesh]) and the search strategy (Persistent Left Superior Vena Cava[Mesh]), applied filters from the years 2018 to 2022 finding a total of 104 articles, of which 88 were eliminated by title and 1 was eliminated by summary. In the end, a total of 14 articles were selected for review.
